ECG BASICS: Sinus Tachycardia in a Toddler

Wed, 05/01/2013 - 19:24 -- Dawn

Here is a nice example of sinus tachycardia taken from a 2-year-old in the post-anesthesia care unit after a short GI endoscopic procedure.  Would you call this NSR, since it is from a child?  The pre-op heart rate in this child was 120/min.

For your more advanced students, remind them that, in adults especially, a heart rate close to 150/min. should cause them to examine the ECG in several leads, looking for the presence of atrial flutter with 2:1 conduction.  Another important teaching point, most ADULTS with sinus tach at 150/min. would  manifest an obvious reason for the rapid heart rate (dehydration, pain, anxiety, shock, etc.)  Challenge your basic students to come up with as many causes for sinus tach as they can.

Jason's Blog: ECG Challenge of the Week for March 10th - 17th. Mutual mimics

These are two 12-lead ECGs that I performed on two completely different patients several years apart. 

Patient's clinical data (Top ECG):
57-year-old black man

Patient's clinical data (Bottom ECG):
67-year-old black man

Are both of these ECGs showing the same rhythmic pattern?

Jason's Blog: ECG Challenge of the Week for Jan. 27th - Feb. 3rd.

Patient's clinical data:  67-year-old white man with a history of COPD and CAD.

Unfortunately, due to the advanced age of this ECG (29-years ago), many details of the device will have to be left to speculation.  I'm unable to retrieve any information about the patient other than the two diagnoses above.

How many different things can you spot in this 12-lead ECG?

Featured Case Study by Guru member Vince DiGiulio, EMT-CC.

This week, in addition to my own blog, I'm going to feature a guest case study by Guru member Vince DiGiulio, EMT-CC.  This past Monday, Vince messaged me (along with Dr. Ken Grauer) on Facebook and requested my input and opinion on these serial ECGs.  With Vince's blessing, he gave me permission to use any of his original 12-lead ECGs here on the Guru.  Of his 6 ECGs, I've decided to post 4 of them here.

Jason's Blog: ECG Challenge of the Week for Dec. 16th - 23rd.

Found this "gem" buried deep-down in the back of the vault and have wanted to share it for many months.  Due to the impressive QRS voltage and overlapping waveforms, I initially debated on whether or not I should post this at 1/2-standard but in the end I decided to retain its original size.  This ECG is from 27 years ago so I have very limited information, but this is what I do know.
